8ae8f9c382 sim: h8300: convert to common sim_{reason,stop} 
This ends up being pretty easy as the h8300 port already supports
much of the common engine core.

7eed1055b8 sim: mcore: pull cpu state out of global scope 
This avoids using global variables to hold the cpu state so we can
better integrate with the sim common code.

There's also a minor fix here where we move the pc register back into
the state that is accessible by the asints array.  When it was pulled
out previously, the reg store/fetch functions broke, but no one really
noticed as the mcore gdb port was dropped a while back.

9ef4651c49 sim: mcore: switch to common sim-reg 
This is not entirely useful as mcore doesn't (yet) store its register
state in the cpu state, but it does allow for switching to the common
code for these functions.

d2dfd24242 sim: clean up redundant objects 
Some of the target makefiles listed objects that were already pulled in
via SIM_NEW_COMMON_OBJS.  Clean those up.

6e4f085c7f sim: sim-close: unify sim_close logic 
Other than the nice advantage of all sims having to declare one fewer
common function, this also fixes leakage in pretty much every sim.
Many were not freeing any resources, and a few were inconsistent as
to the ones they did.  Now we have a single module that takes care of
all the logic for us.

Most of the non-cgen based ones could be deleted outright.  The cgen
ones required adding a callback to the arch-specific cleanup func.
The few that still have close callbacks are to manage their internal
state.

We do not convert erc32, m32c, ppc, rl78, or rx as they do not use
the common sim core.

9bea4d16a6 sim: testsuite: support basic vars in flags 
Sometimes in tests, we need supplemental files like linker scripts or
board helper files.  There's no way to set those flags in the tests
currently and relative paths don't work (breaks out of tree builds).

Update the main option parser to replace some strings on the fly.  Now
tests can do things like:

Long term we'll want to switch the framework to use the dejagnu helpers
like dg-xxx that gcc & gdb utilize.  But that'll require more rework.

c4d4ed4083 sim: drop extern C linkage from most sim interface headers

c4312b1985 PR 19051: support of inferior call with gnu vector support on ARM 
This patch teaches GDB to support gnu vector in inferior calls.  As a
result, fails in gdb.base/gnu_vector.exp are fixed.  The calling
convention of gnu vector isn't documented in the AAPCS, because it
is the GCC extension.  I checked the gcc/config/arm/arm.c, understand
how GCC pass arguments and return values, and do the same in GDB side.

The patch is tested with both hard float and soft float on arm-linux.

b13c8ab2b9 Refactor arm_return_in_memory 
Current arm_return_in_memory isn't friendly to adding new things in it.
Moreover, a lot of stuff are about APCS, which is not used nowadays (AAPCS
is being used).  This patch is to refactor arm_return_in_memory, so that
some code can be shared for both APCS and AAPCS at the beginning of
arm_return_in_memory, and then each ABI (APCS and AAPCS) are processed
separately.

This patch removes the leftover of the d10v stuff in the testsuite

77ae9c1933 gdb.base/gnu_vector.exp: Don't test output from the inferior 
gdb.base/gnu_vector.c printf the vector and gdb.base/gnu_vector.exp
expects the output by gdb_test_multiple.  Nowadays, the test doesn't
expect the output from inferior_spawn_id, which is wrong.  Even we
change the test to expect from inferior_spawn_id for the inferior
output, it is still possible the inferior exit before tcl/expect gets
the inferior output.  We see this fail on both s390x-linux and
ppc-linux on buildbot,

  FAIL: gdb.base/gnu_vector.exp: verify vector return value (the program exited)

https://sourceware.org/ml/gdb-testers/2015-q4/msg04922.html
https://sourceware.org/ml/gdb-testers/2015-q4/msg04952.html

In order to address these two shortcomings above in gnu_vector.exp,
this patch rewrites the test a little bit.  Get rid of checking the
inferior output, and instead checking them by printing them.  In this
way, the test can also be run on the target without inferior io
(gdb,noinferiorio is set in the board file).

9c352f1c23 [AArch64] Add support for Cortex-A35 
This patch adds support to the AArch64 back-end for the Cortex-A35
processor, as recently announced by ARM. The ARM Cortex-A35 provides
full support for the ARMv8-A architecture, including the CRC extension,
with optional Advanced-SIMD and Floating-Point support. We therefore set
feature flags for this CPU to AARCH64_ARCH_V8 and AARCH64_FEATURE_CRC, in
the same fashion as Cortex-A53 and Cortex-A57.

Tested in a cross environment for AArch64 with no issues.

dddc0e16ef [Ada] GDB crash during "finish" of function with out parameters 
Consider a function with the following signature...

   function F (R : out Rec_Type) return Enum_Type;

... where Rec_Type is a simple record:

   type Rec_Type is record
      Cur : Integer;
   end record;

Trying to "finish" from that function causes GDB to SEGV:

    (gdb) fin
    Run till exit from #0  bar.f (r=...) at bar.adb:5
    0x00000000004022fe in foo () at foo.adb:5
    5          I : Enum_Type := F (R);
    [1]    18949 segmentation fault (core dumped)  /[..]/gdb

This is related to the fact that funtion F has a parameter (R)
which is an "out" parameter being passed by copy. For those,
GNAT transforms the return value to be a record with multiple
fields: The first one is called "RETVAL" and contains the return
value shown in the source, and the remaining fields have the same
name as the "out" or "in out" parameters which are passed by copy.
So, in the example above, function F returns a struct that has
one field who name is "r".

Because "RETVAL" starts with "R", GDB thinks it's a wrapper field,
because it looks like the encoding used for  variant records:

   --    member_name ::= {choice} | others_choice
   --    choice ::= simple_choice | range_choice
   --    simple_choice ::= S number
   --    range_choice  ::= R number T number   <<<<<-----  here
   --    number ::= {decimal_digit} [m]
   --    others_choice ::= O (upper case letter O)

See ada_is_wrapper_field:

  return (name != NULL
          && (startswith (name, "PARENT")
              || strcmp (name, "REP") == 0
              || startswith (name, "_parent")
              || name[0] == 'S' || name[0] == 'R' || name[0] == 'O'));

As a result of this, when trying to print the RETURN value,
we think that RETVAL is a wrapper, and thus recurse into
print_field_values...

      if (ada_is_wrapper_field (type, i))
        {
          comma_needed =
            print_field_values (TYPE_FIELD_TYPE (type, i),
                                valaddr,
                                (offset
                                 + TYPE_FIELD_BITPOS (type, i) / HOST_CHAR_BIT),
                                stream, recurse, val, options,
                                comma_needed, type, offset, language);

... which is a problem since print_field_values assumes that
the type it is given ("TYPE_FIELD_TYPE (type, i)" here), is also
a record type. However, that's not the case, since RETVAL is
an enum. That eventually leads GDB to a NULL type when trying to
extract fields out of the enum, which then leads to a SEGV when
trying to dereference it.

Ideally, we'd want to be a little more careful in identifying
wrapper fields, by enhancing ada_is_wrapper_field to be a little
more complete in its analysis of the field name before declaring
it a variant record wrapper. However, it's not super easy to do
so, considering that the choices can be combined together when
complex choices are used. Eg:

   -- [...] the choice 1 .. 4 | 7 | -10 would be represented by
   --    R1T4S7S10m

Given that we are working towards getting rid of GNAT encodings,
which means that the above will eventually disappear, we took
the more pragmatic approach is just treating  RETVAL as a special
case.

        * ada-lang.c (ada_is_wrapper_field): Add special handling
        for fields called "RETVAL".
